Laparoscopic liver resection (LLR) has garnered attention as a new form of liver surgery. In China, many hepatobiliary surgeons are now encouraging the examination and assessment of LLC in order to improve its outcomes, and several young hepatobiliary surgeons recently shared their clinical experiences and the results of their research in presentations at the Akamon Forum as part of the 118th Annual Congress of the Japan Surgical Society, which was held April 5-7, 2018 in Tokyo, Japan. In China, LLR has gradually improved over the past 20 years, including both expanded indications and improved surgical approaches...

BACKGROUND: We previously developed an image-guided navigation system (IG-NS) using augmented reality technology for hepatobiliary and pancreatic (HBP) surgery. This system superimposed a 3D model onto a stereoscope-captured surgical field (i.e., the scope method). Unfortunately, this method requires an expensive stereoscope, surgeons have to shift their eyesight away from the surgical field, and the method has poor controllability. Therefore, an IG-NS using a tablet PC (i.e., the tablet method) was developed...

Since their initial description, perihilar cholangiocarcinoma (pCCA) has remained one of the more clinically challenging scenarios encountered by hepatobiliary surgeons. Surgery remains the only potentially curative therapy, but requires complex, technically demanding operations with high associated morbidity and mortality. Over the last several decades, advances in surgical technique and perioperative management have improved patient outcomes. Areas Covered: Achievement of optimal outcomes requires a multidisciplinary approach from a team of providers with expertise in hepatobiliary and oncologic surgery, medical oncology, radiation oncology, and advanced gastroenterology...

Muhammad Shafiq, Yousaf Zafar
Acute acalculous cholecystitis (AAC) is most commonly seen after surgery in critically ill patients. Early diagnosis and treatment is the key in the management of AAC. Ultrasound is the commonly used first modality for right upper quadrant (RUQ) pain with sensitivity equal to or greater than 80% for AAC. Computed tomography (CT) scan is reported to have a sensitivity close to 90% and if both the ultrasound and CT scan are combined, it further increases the sensitivity for the diagnosis of AAC. It is unlikely for AAC to be present in the setting of both negative ultrasound and CT scan of the abdomen...

Intraoperative hypothermia occurs frequently, but hyperthermia is relatively rare during general anesthesia. We experienced a case of hyperthermia during living donor liver transplantation that appeared to be significantly associated with biliary obstruction. A 65-year-old male patient was diagnosed with intrahepatic cholangiocarcinoma, and living donor liver transplantation was planned after confirmation of no metastasis via intraoperative frozen biopsy. Following resection of a segment of common bile duct for frozen biopsy, the surgeon clamped the common bile duct, and the patient's body temperature increased gradually to 39...

More than 9000 laparoscopic liver resections (LLR) are performed worldwide for benign lesions, malignancy (mainly for hepatocellular carcinoma and colorectal cancer liver metastasis), and living donor hepatectomy. Although there is no absolute size criterion, smaller, peripheral lesions (<5 cm) of the anteriolateral segments, that lie far from major vessels and anticipated transection planes are most amenable to LLR, but nowadays lesions of the less ideal posterosuperior segments are feasible for LLR too...

BACKGROUND: Augmented reality (AR) technology is used to reconstruct three-dimensional (3D) images of hepatic and biliary structures from computed tomography and magnetic resonance imaging data, and to superimpose the virtual images onto a view of the surgical field. In liver surgery, these superimposed virtual images help the surgeon to visualize intrahepatic structures and therefore, to operate precisely and to improve clinical outcomes. DATA SOURCES: The keywords "augmented reality", "liver", "laparoscopic" and "hepatectomy" were used for searching publications in the PubMed database...

Fathima Kamil, Julie H Rowe
The tumor microenvironment (TME) is defined as the structural and dynamic network of cellular and non-cellular interactions between malignant cells and the surrounding non-malignant matrix. Hepatocellular carcinoma (HCC) and pancreatic ductal adenocarcinoma (PDAC) are two of the most challenging gastrointestinal malignancies. Despite clinical advancements in understanding tumor biology and growth of the chemotherapeutic industry, there have been no corresponding improvements in prognosis and overall survival of HCC and PDAC...
